Abstract
355,071. Induction motors. SWENDSEN, J. W., 9. Klingenberggaten, Oslo, Norway. Sept. 18, 1930, No. 27928. Convention date, Sept. 19, 1929. Addition to 339,206, [Class 35, Dynamo-electric generators &c.]. [Class 35.] In an induction motor as in the parent Specification comprising one or more ring-shaped stators and a rotor consisting of two or more ring-shaped magnetic elements, the short-circuited bars for each pair of rotor elements adjacent to one stator consists of U-shaped bars with one limb of each passing through one of the rotor elements so that the ends project outside the periphery of the rotor elements where they are joined by means of shortcircuiting rings. The stator 11 is secured to the frame 13 by legs 12 and has a ring-winding 14. The rotors 17,18 are slotted to receive the U-shaped bars 28, the ends of which are welded or otherwise secured to short-circuiting rings 31, 32. The rings are spaced away from the cores to ensure adequate cooling. Shields 33, 34, preferably divided into halves, may be screwed to the short-circuiting rings to reduce flux leakage. The stator and rotor cores are formed by winding a strip of metal into a coil.
